Purpose of this paper is investigating if the effect of diffusion bonding parameters on the microstructure and mechanical properties of the joints. Design/methodology/approach: Titanium and X5CrNi18-10 stainless steel samples were joined by diffusion bonding using copper foil as a filler metal at temperatures of 850, 875, 900, 925, 950 and 1000°C. From the stainless steel site of joint in all samples,...
Purpose: A route to manufacture porous carbon fiber reinforced plastic (CFRP) for study purposes is described. Design/methodology/approach: The porous CFRP is characterized using standard techniques such as matrix digestion as well as the more sophisticated method of high resolution Microfocus X-Ray Tomography (μCT). A comparison of the results of those methods is presented. The mass gains of specimens...
Purpose: The aim of this research is presented ceramic injection moulding process of alumina parts. Firstly alumina parts was performed by using binder system. The binder consisted of a mixture of a polypropylene (PP), paraffin wax (PW) and stearic acid (SA). Design/methodology/approach: The volume fractions of powder in the feedstocks were changed from 40-50%vol and the volume of polypropylene were...
Purpose: The aim of this paper was to determine the strength and elasticity of low melting point alloys. In particular, the laboratory tests were observed to check the shape of the compression curve. This is a result of recrystallization. Design/methodology/approach: The strength and stiffness of the low melting point alloys was found. The unusual shape of the compression curve was observed. In order...
Purpose: Investigation of joining γ-titanium aluminides using Al interlayers. Design/methodology/approach: : In order to achieve a proper joining of TiAl elements, a method known as Transient Liquid Phase (TLP) bonding was combined with Spark Plasma Sintering (SPS). All the experiments were performed under a uniaxial pressure of 7.4 MPa in a vacuum to prevent possible oxidation of liquid Al in the...
Purpose: This paper describes research results of Laser Beam Welding of Ti/Al thin sheets in which many researchers have recently performed and critically reviewed from different perspectives. Design/methodology/approach: Some of notable works in the field of laser welding with changes in mechanical properties, crack propagation, diffusion behaviour, chemical potential, interfacial reaction and the...
